MINERAL  INDUSTRY,  CALIFORNIA,  1912. 


Data  Compiled  from  Direct  Returns  from  Producers  in  Answer  to 

Inquiries  sent  out  by  California  State  Mining  Bureau, 

Ferry  Building,  San  Francisco. 


CHAPTER  ONE. 

Taking  the  mineral  industry  in  California  as  a  whole  the  year  1912 
was  one  of  unexampled  progress  and  prosperity.  The  greatest  single 
product,  petroleum,  excelled  even  the  remarkable  rate  of  growth  which 
it  has  manifested  during  the  past  ten  years.  "While  the  average  price 
per  barrel  received  for  crude  oil  at  the  wells  showed  a  slight  decline 
as  compared  with  that  of  the  previous  year,  the  consumption  increased 
at  a  greater  rate  than  the  production,  and  the  threatened  oversupply, 
^vhich  seemed  to  be  imminent  at  the  end  of  1911,  was  entirely  dissi- 
pated. Development  of  the  light  gravity  oil  districts  of  the  State  has 
been  active  and  most  encouraging  results  have  ensued.  This  fact,  taken 
with  the  ever  growing  demand  for  crude  petroleum  and  all  its  deriva- 
tives has  given  an  added  impetus  to  the  industry  and  the  present 
trend  of  both  production  and  price  is  decidedly  upward.  Petroleum 
leads  all  other  mineral  products  of  the  State  by  a  wide  margin,  the 
value  for  1912  being  $41,868,344. 

Next  in  importance  comes  gold  with  an  output  of  $19,713,478.  The 
great  deep  mines  of  the  State  maintain  a  steady  output  which  is 
31' I  nothing  less  than  remarkable.  At  several  properties  extensive  develop- 
ji|  ment  work  has  been  done  during  the  year  with  an  idea  of  determining 
jiji  the  probability  of  obtaining  continued  values  at  depth,  with  most 
jjp  satisfying  results.  While  the  zenith  of  the  dredge  production  is  prob- 
51,  ably  at  hand,  increased  efficiency  in  methods  has  offset  the  fact  that 
^:  the  richest  of  the  gravel  deposits  have  been  rather  completely  worked 
o!|'  out.  There  is  at  present  nothing  to  indicate  any  decrease  in  Cali- 
fornia's output  of  the  precious  metal. 

Cement  ranks  third  with  an  output  valued  at  $6,074,661;  copper  is 
number  four  on  the  list  with  $5,638,049. 

Crushed  rock,  brick  and  borax  follow,  in  the  order  of  their  import- 
ance, each  with  a  production  worth  over  the  million  dollar  mark. 

Every  one  of  California's  fifty-eight  counties  contain  mineral 
deposits  of  some  description.  During  1912  fifty-six  counties  produced 
commercially  one  or  more  mineral  substance. 


b  MINERAL    INDUSTRY    OF    CALIFORNIA. 

The  total  value  of  these  minerals  was  $88,972,385,  as  compared  wit) 
$87,497,879  for  1911,  an  increase  of  $1,474,506.  These  figures  do  not 
include  value  of  asphalt  because  of  the  fact  that  the  asphalt  used  in 
the  State  is  a  refined  product  and  as  far  as  possible  all  data  in  thi^ 
report  refers  to  Crude  Materials,  with  values  of  same  at  the 
PROPERTY.  In  this  connection,  however,  it  is  worthy  of  note  that  the 
asphalt  production  for  1912  amounted  to  approximately  250,000  tons, 
with  a  total  value  of  $2,500,000.  This  item  is  often  included  in| 
estimating  the  mineral  output  for  the  State  and  it  is  well  to  bear  m 
mind  the  fact  that  it  is  omitted  in  the  annual  totals  above  quoted. 

While  the  more  prominent  and  well  known  minerals  show  a  consist- 
ently increasing  production,  it  is  gratifying  to  note  that  the  leas 
common  metals  and  industrial  materials  are  also  coming  in  for  their 
share  of  attention.  Zinc,  tungsten,  marble,  soapstone,  pumice,  and 
many  other  substances  exhibit  an  increased  production.  The  immense 
iron  deposits  practically  untouched  as  yet;  the  mountains  of  building 
stone  of  every  description;  the  inexhaustible  deposits  of  oil,  gold  and 
copper;  the  millions  of  acres  of  saline  deposits  in  the  desert  regions, 
all  go  to  prove  the  truth  of  the  statement  that  California's  wonderful 
record  as  a  mineral  producer  will  increase,  rather  than  diminish,  foi 
many  years  to  come. 

Borax,  magnesite  and  chrome  production  for  the  United  States  come 
solely  from  California.  Eighty  per  cent  of  the  domestic  supply  of 
quicksilver  is  mined  here ;  the  same  figures  hold  true  in  the  case  of 
platinum;  tungsten  is  produced  in  but  two  or  three  other  States. 
California  leads  all  other  states  in  the  Union  in  the  value  of  petroleum 
and  gold  produced;  is  first  of  all  states  west  of  the  Mississippi  in  the 
value  of  her  total  mineral  production,  and  is  only  outranked  by  a  ie^ 
of  the  great  iron  and  coal  producing  states  of  the  East. 

Kern  leads  all  other  counties  in  petroleum  production;  Amador  and 
Yuba  are  close  rivals  for  first  place  in  gold  output;  Shasta  produces] 
80  per  cent  of  the  copper  total ;  Los  Angeles  leads  in  brick  and  crushed 
rock ;  Inyo  is  first  in  borax,  lead,  soda  and  zinc ;  San  Benito  is  first  in 
quicksilver  production;  San  Diego  County  produces  half  of  the  gems 
found  in  the  State;  Placer  is  first  in  granite  and  building  stone; 
Santa  Cruz  in  lime;  Tulare  in  magnesite;  Tuolumne  in  marble;  Ala- 
meda in  salt,  and  Colusa  in  sandstone.

The  figures  opposite  * '  unapportioned "  are  necessary  because  of 
fact  that  some  branches  of  the  mineral  industry  are  so  centrali: 
that  if  the  value  of  their  output  were  listed  under  the  county  fr( 
which  they  come  private  business  would  be  made  public.     For  t 
reason  there  are  several  instances  where  the  real  value  of  the  coui

CHAPTER  TWO. 

FUELS, 
(t. 

Reference-  State  Mineralogist  Eeport  VII,  XII,  XIII. 

Twenty-five,  out  of  the  fifty-eight,  counties  of  California  contain 
coal  deposits,  many  of  them  undeveloped,  and  almost  all  of  an  interior 
quality.  Coal  was  first  commercially  produced  in  the  State  in  1861 
and  for  many  years  previous  to  the  introduction  of  petroleum  as  a  fuel 
was  an  important  factor  in  the  mineral  industry  of  the  State.  At  the 
present  time  the  output  is  small  and  the  price  received  relatively  low, 
and  fluctuating.  During  1912  the  total  coal  production  amounted  to 
14,848  tons  valued  at  $39,092,  an  average  of  $2.63  per  ton,  as  com- 
pared with  11,047  tons  produced  in  1911  having  a  spot  value  of 
$18,297,  or  $1.65  per  ton.  This  is  an  increase  of  3,801  tons  in  amount, 
and  $20,795  in  value,  the  excessive  increase  in  price  being  due  to  the 
production  of  a  better  grade  of  coal  than  was  mined  during  the  pre- 
ceding year,  as  well  as  to  a  noticeable  strengthening  in  the  local  demand, 

I  Natural  Gas. 

Reference:  State  Mineralogist  Report  VII,  X,  XII.     Bulletins  3 
and  13. 
Natural  gas  valued  at  $940,076  was  used  as  a  fuel,  for  lighting,  and 
for  other  purposes,  including  the  manufacture  of  gasoline,  during  1912, 

,  in  California.  This  shows  a  great  increase  over  the  value  of  the  1911 
product  which  was  $491,859. 

I     Active  steps  have  been  recently  taken  toward  the  conservation  of 

!  natural  gas  in  the  State,  untold  quantities  of  which  have  been  lost  and 
wasted  in  the  past. 

It  is  impossible  to  arrive  at  even  approximate  figures  for  amount  of 
gas  used  as  in  many  cases  the  operators  make  no  attempt  to  measure 

!  it;  the  value  as  well,  in  numerous  instances,  represents  merely  an 
approximation,  especially  in  the  case  of  oil  operators  who  utilize  a 
portion  of  the  gas  which  is  encountered  as  fuel  under  their  boilers  and 
figure  its  value  in  terms  of  what  it  would  cost  to  obtain  the  required 
power  in  some  other  wav.

Report  IV,  X,  XII,  XIII. 

Petroleum  production  in  California  during  1912  amounted  to  a  total* 
of  89,689,250  barrels,  valued  at  $41,868,344,  or  an  average  of  $0.467| 
per  barrel  as  compared  with  84,648,157  barrels  produced  in  1911  worth 
$40,552,088  with  an  average  price  of  $0,479  per  barrel.  This  is  ani 
increase  in  amount  of  5,041,093  barrels  and  in  value  of  $1,316,256,  but 
a  decrease  in  the  price  received  per  barrel  of  $0,012. 

Of  the  total  number  of  barrels  produced  in  1912,  6,050,186  were 
used  as  fuel  in  the  field.  This  item,  which  has  always  been  a  com- 
paratively large  one,  is  gradually  diminishing  on  account  of  the  grow- 
ing use  of  electricity  and  gas  in  the  oil  fields  for  power  purposes. 

Considerable  successful  development  work  was  done  during  the  year^ 
in  the  lighter  oil  sections  of  the  State,  and  in  the  face  of  a  decrease  in 
the  average  price  per  barrel  for  the  State,  Orange,  Santa  Barbara  andf 
Ventura  counties  reported  an  increase  in  price,  as  well  as  production.! 
The   only  section   which   suffered   a    decreased   production   was   Los 
Angeles  County — this  is  due  partly  to  the  fact  that  the  city  field  isj 
rapidly  becoming  more  valuable  as  real  estate  than  it  is  as  oil  territory, 
and  more  especially  because  w^e  have  some  of  the  oldest  producing  wells 
in  the  State,  and  many  of  them  are  rapidly  approaching  the  end  of  their 
days  as  profitable  producers. 

The  following  table  gives  in  detail  the  production  and  value  of 
petroleum  produced  in  California  in  1912,  and  the  corresponding  figures 
for  1911,  by  county,  as  well  as  the  average  prices  received,  with  increase,

Antimony. 

Eeference:  Bulletin  38.     State  Mineralogist  Report  XII,  XIII. 

Deposits  of  antimony  ore  are  located  in  Inyo,  Kern,  Merced,  Eiver- 

le  and  San  Benito  counties.     There  has  been  no  commercial  produe- 

II  on  of  the  metal  in  California  since  1901,  principally  because  of  the 

fact  that  prices  have  been  too  low  to  make  the  mining  of  the  ore 

profitable. 

Copper. 

Reference:  Bulletins  23  and  50.     State  Mineralogist  Report  XIT, 

XIII. 

For  the  calender  year   1912  the  California  production  of  copper 

amounted  to  34,169,997  pounds,  valued  at  $5,638,049  as  compared  with 

:>G,838,024  pounds  produced  in  1911  worth  $4,604,753.     The  increased 

value,  in  spite  of  the  decrease  in  production,  was  made  possible  on 

account  of  the  advance  in  price  from  12^  cents  per  pound  in  1911,  to 

16J  cents  per  pound  in  1912. 

Copper  is  widely  distributed  throughout  the  State  in  the  following 

iieral  districts:     The  Shasta  County  copper  belt;  the  Coast  Range 

posits,  running  from  Del  Norte  more  or  less  continuously  to  San 

Luis  Obispo  County ;  the  Sierra  Nevada  belt,  starting  in  Plumas  County 

and  continuing  in  a  general  southerly  direction  through  the  Mother 

Lode  counties  and  ending  in  Kern ;  the  Eastern  belt,  in  Mono  and  Inyo 

counties;  and  the  Southern  belt,  which  is  located  in  San. Bernardino, 

Riverside  and  San  Diego  counties.     By  far  the  most  important  belt  is 

the  one  located  in  Shasta  County. 

Copper  production  has  been  far  below  normal  in  the  State  during  the 
past  few  years  on  account  of  the  enforced  closing  of  some  of  the  largest 
smelters  owing  to  the  alleged  damage  done  to  the  surrounding  agricul- 
tural products  by  the  smelter  smoke.  A  great  deal  of  money  has  been 
spent  in  an  effort  to  do  away  with  the  obnoxious  fumes  with  consid- 
erable success,  and  the  present  outlook  is  for  a  greatly  increased  pro- 
I   duction  in  the  near  future.

MINERAL  INDUSTRY   OF   CALIFORNIA. 


It  will  be  observed  that  the  largest  production  for  any  one  year  was 
in  1852,  when  it  reached  $81,294,700.  This  was  at  the  time  of  the  most 
active  development  of  the  superficial  placers,  when  thousands  of  men 
were  at  work  with  pan,  rocker,  long-torn  and  sluice,  and  even  the 
hydraulic  method  had  been  introduced  in  a  small  way. 
Iron. 

Reference:  State  Mineralogist  Reports  II,  IV,  V,  X,  XII,  XIII. 
Bulletin  38. 

Production  of  iron  ore  in  California  during  1912  amounted  to  2,508 
tons,  having  a  spot  value  of  $1  per  ton.  This  is  a  very  notable 
increase  over  the  1911  production  of  558  tons.  There  was  a  small  out- 
put of  this  mineral  in  1893  and  nominal  amounts  have  been  produced 
intermittently  since  that  time,  the  entire  production  previous  to  1912 
amounting  to  2,095  tons,  or  413  tons  less  than  for  the  year  just  past. 
Vast  deposits  of  iron  ore,  distributed  through  thirty-one  counties  of 
the  State,  are  already  known.  With  improvements  in  the  metallurgy 
of  iron  and  steel,  the  changes  to  be  wrought  in  commercial  conditions 
by  the  opening  of  the  Panama  Canal,  and  the  gradual  depletion  of 
the  iron  ranges  of  the  East,  this  branch  of  the  mineral  industry  in 
California  should  soon  become  one  to  rank  with  petroleum  and  gold  in 
the  value  of  its  output.  ' 

Lead. 

Reference:  State  Mineralogist  Reports  IV,  VIII,  X. 

Thirteen  counties  in  California  reported  a  production  of  lead  for 
1912.  In  four  instances,  namely,  Butte,  Calaveras,  El  Dorado  and 
Placer  counties,  the  output  was  negligible  being  recovered  from  con- 
centrates shipped  to  the  smelter  and  having  values  of  but  a  few  dollars. 
The  total  lead  production  for  the  State  amounted  to  1,370,067  pounds, 
valued  at  $61,653,  as  compared  with  an  output  of  1,403,839  pounds 
worth  $63,173  in  1911.  The  average  price  of  lead  during  1912  was 
4 J  cents  per  pound.

Molybdenum. 

Deposits  of  molybdenite  have  been  observed  in  different  localities  in 
California  in  the  past  but  no  molybdenum  has  been  commercially  pro- 
duced, to  date.  It  is  used  to  a  small  extent  in  steel  making  and  has 
recently  been  successfully  used  as  an  improvement  over  tungsten  in 
electric  light  globes.  Some  development  work  has  been  done  on  molyb- 
denum deposits  in  Kern  County  during  the  past  year. 

Platinum. 

Reference:  State  Mineralogist  Reports  XII,  XIII.  Bulletin  38. 
Platinum  production  in  California  during  the  year  1912  amounted 
to  603  ounces,  worth  $19,731,  as  compared  to  511  Troy  ounces,  valued 
at  $14,873,  in  1911.  Platinum  yield  in  the  State  is  largely  due  to  its 
incidental  recovery  alonir  with  placer  gold  in  various  dredging  and 
hydraulic  fields. 

Quicksilver. 

Reference:  State  Mineralogist  Reports  IV,  X,  XII,  XIII.  Bul- 
letin 27. 

Quicksilver  production  in  California  during  1912  amounted  to  20,600 
flasks  having  a  total  value  of  $866,024,  an  average  of  $42.04  per  flask, 
as  compared  with  the  1911  output  of  19,109  flasks  valued  at  $879,205. 
The  average  price  per  flask,  of  75  pounds,  suffered  a  decrease  of  $3.97 
in  1912,  as  compared  with  the  previous  year,  thus  causing  a  decrease  of 
1.5  per  cent  in  the  total  value  of  the  metal  produced  while  the  amount 
increased  7.8  per  cent. 

Eight  counties  reported  a  production  of  quicksilver  during  1912 
against  nine  for  1911.  Colusa  and  Santa  Barbara  counties  had  a  small 
output  in  1911  which  was  not  duplicated  last  year,  and  during  1912 
Fresno  County  operators  shipped  a  quantity  of  the  metal  for  the  first 
time.  The  eight  producing  counties,  in  the  order  of  their  importance 
in  this  branch  of  the  mineral  industry,  are  as  follows:  San  Benito, 
Santa  Clara,  San  Luis  Obispo,  Sonoma,  Fresno,  Napa,  Lake  and  Trinity. 
In  addition  to  the  above,  owners  of  quicksilver  properties  from  the 
foUowinsT  tweh'e  counties  answered  inquiries  sent  out  by  the  State 
Mining  Bureau:  Colusa,  El  Dorado,  Kings,  Monterey,  Modoc,  Santa 
Barbara,  Shasta,  Siskiyou,  Solano,  Stanislaus  and  Yolo.  In  round 
numbers  80  per  cent  of  the  quicksilver  production  of  the  United  States 
comes  from  California.

collected  by  the  United  States  Geological  Survey,  from  which  source 
these  figures,  along  with  those  of  gold  and  platinum,  are  derived.  The 
average  price  for  silver  for  1912  was  61|^  cents,  or  8J  cents  per  ounce 
higher  than  for  1911.

Tungsten. 

Reference:  Bulletin  38. 
Tungsten  ore  to  the  amount  of  8,042  tons  containing  tungsten  valued 
at  $206,000  was  mined  in  California  during  1912.     The  value  of  the 
tungsten  output  for  1911  was  $127,706. 


STATE    MINING    BUREAU    STATISTICS.  21 

This  metal  is  used  largely  in  the  steel  industry  and  also  as  a  filament 
in  electric  incandescent  lamps. 

Tungsten  ores  are  sold  per  unit  of  tungstic  trioxide,  marketable  ores 
arrying  at  least  45  per  cent  of  WO^. 

Tin. 

While  there  are  several  deposits  of  tin  ore  in  the  United  States  the 
production  for  the  entire  country  is  practically  nothing.  A  small 
deposit  of  cassiterite  near  Corona,  in  Eiverside  County,  was  worked  in 
the  early  nineties  and  tin  to  the  value  of  $59,964  was  produced.  The 
deposit  is  very  small  and  irregular  and  no  development  work  has  been 
done  on  it  for  many  years.  Traces  of  tin  ore  have  also  been  discovered 
in  Orange  County. 

Vanadium. 

There  is  a  growing  demand  for  vanadium  for  use  particularly  in  the 
eel  industry.     California  has  never  produced  this  metal  commercially, 

but  deposits  of  vanadium  ores  are  at  present  being  exploited  in  two  or 

three  localities. 

Zinc. 

Beference:  Bulletin -38. 
During  1912  zinc  to  the  amount  of  4,331,391  pounds,  with  a  total 
value  of  $298,866  was  produced  in  California,  as  compared  with  2,679,- 
842  pounds  worth  $152,751  in  1911.  The  average  price  per  pound 
received  for  zinc  during  1912  was  $.069.  A  small  quantity  of  this 
metal  was  mined  in  the  State  in  1906-8  and  with  this  exception  1911 
was  the  first  year  to  show  returns  from  this  branch  of  the  mineral 
industry.  As  will  be  noted  the  output  was  practically  doubled  in  1912 
as  compared  with  the  previous  year.  Zinc  ores  are  found  in  Inyo, 
Orange,  San  Bernardino  and  Shasta  counties ;  zinc  is  also  an  ingredient 
of  many  copper  and  other  ores  in.  various  portions  of  the  State.

STRUCTURAL  MATERIALS. 


Asphalt. 

Reference:  State  Mineralogist  Reports  VII,  X,  XII,  XIII.     Bul- 
letins 16  and  32. 

Deposits  of  natural  asphalt  have  been  found  in  Kern,  Los  Angekv  . 
Monterey,  San  Luis  Obispo,  Santa  Barbara,  Santa  Clara,  Santa  Cruz 
and  Ventura  counties.  In  recent  years  refined  asphalt,  only,  has  been 
used  commercially  because  a  better  grade  can  be  produced  for  less 
money  than  the  deposits  of  natural  asphalt  afford.  In  round  numbers 
the  refined  product  sold  in  1912  amounted  to  250,000  tons  valued  at 
$2,500,000,  or  $10  per  ton.  This  is  an  increase  of  70,000  tons  over  the 
corresponding  production  during  1911,  although  the  price  per  ton 
decreased  about  $2.  Over  forty  oil  refineries  are  in  operation  in  Cali- 
fornia situated  in  the  following  counties:  Alameda,  Contra  Costa, 
Fresno,  Kern,  Los  Angeles,  San  Diego,  Santa  Barbara,  San  Luis  Obispo, 
San  Francisco  and  Ventura. 

Asphalt  is  used  principally  in  street  paving ;  also  for  roofing,  insulat- 
ing, preservative  of  piling,  etc. 

Production  figures  for  asphalt  are  not  added  to  the  total  of  the 
State's  mineral  output  because  it  is  included  in  the  value  of  the  crude 
petroleum  from  which  it  is  manufactured  and  the  addition  of  the  value 
of  this  by-product  would  give  an  erroneous  result,  too  high  by  the 
above  amount,  i.  e.,  $2,500,000  for  the  year  1912. 
Bituminous  Rock. 

Reference:  State  Mineralogist  Reports  XII,  XIII. 

Production  of  bituminous  rock  in  California  amounted  to  44,073 
tons  valued  at  $87,467  for  the  year  1912,  output  being  reported  from 
San  Luis  Obispo,  Santa  Barbara  and  Santa  Cruz  counties.  This  is  a 
considerable  decrease  from  the  1911  figures  when  75,125  tons  were  pro- 
duced worth  $117,279. 

Solano  County,  which  was  the  largest  producer  in  1911  reported  no 
output  of  bituminous  rock  during  1912,  the  product  which  had  deteri- 
orated somewhat  in  quality  being  used  merely  as  crushed  rock,  and 
classified  as  such. 

Santa  Barbara  County  is  a  new  producer  of  this  material.

Brick. 

Reference:  Bulletin  38. 

The  total  brick  production  in  California  during  the  year  1912 
amounted  to  337,233  M,  valued  at  $2,940,290,  as  compared  with  an 
output  of  327,474  M  Worth  $2,638,121  in  1911,  or  an  increase  in  amount 
of  9,759  M,  and  in  value  of  $302,169. 

Twenty-five  counties  contributed  to  the  above  total  and  a  gpeat  variety 
of  brick  was  produced,  including  common,  fire,  pressed,  glazed,  sand 
lime,  and  others.  An  attempt  has  been  made  to  segregate  the  figures 
for  the  different  kinds  of  brick,  as  will  be  noted  in  the  following  county 
tabulation.  In  many  cases  reports  from  operators  of  brick  kilns  make 
no  classification.  Such  figures  are  necessarily  listed  as  "miscellaneous. " 
Therefore  it  will  be  understood  that  the  totals  under  the  different  head- 
ings are  low  in  each  classification. 

According  to  Bulletin  No.  38,  issued  by  the  California  State  Mining 
Bureau,  the  following  analyses  show  the  average  and  the  maximum  and 
minimum  of  the  ingredients  commonly  occurring  in  brick  clays.  A  clay 
in  which  the  percentage  of  any  one  or  more  of  the  ingredients  mentioned 
is  much  above  the  maximum  given  or  below  the  minimum  will  prove  an 
inferior,  if  not  worthless,  clay  for  even  common  brick.

Cement. 

Reference :  State  Mineralogist  Reports  VIII,  IX.  XII.     Bulletin  38. 
During  1912   California's  output  of  cement  was   6,198,634  barrels 
ilued  at  $6,074,661,  as  compared  with  6,371,369  barrels  produced  in 
111  having  a  value  of  $9,085,625.     The  cement  industry  is  so  cen- 
tralized that  it  is  impossible  to  apportion  the  production  to  the  counties 
in  which  the  plants  are  located  without  making  private  business  public. 
Cement  was  first  commercially  produced  in  the  State  in  1891.     While 
the  total  figures  are  not  of  the  same  magnitude  as  those  for  gold  and 
■troleum  the  growth  of  the  industry  has  been  more  than  rapid,  and  a 
'iiiparison  of  the   annual  figures  representing  the  output  since  the 
inception  of  the  industry  is  of  interest.

Chrome. 

Reference:  State  Mineralogist  Reports  IV,  XII.  Bulletin  38. 
In  1912  chrome  production  to  the  amount  of  1,270  tons,  having  a  spot 
value  of  $11,260,  was  reported  from  Shasta,  Siskiyou  and  Fresno 
counties.  The  1911  output  was  935  tons  valued  at  $14,197,  showing  a 
gain  in  amount  for  1912  of  335  tons,  and  a  loss  in  value  of  $2,937.  The 
decrease  in  price  was  due  to  the  production  of  an  inferior  grade  of  ore 
as  compared  with  that  of  the  previous  year.  Chrome,  or  more  correctly, 
chromic  iron  ore,  is  used  principally  as  the  refractory  ingredient  in 
reverberatory  and  other  furnace  linings.  The  quantity  of  this  ore  in 
California,  which  is  the  sole  source  of  domestic  supply,  far  exceeds  the 
demand,  large  deposits  being  known  in  Sonoma,  Tehama,  Tuolumne  and 
other  counties,  in  addition  to  those  mentioned  above.

Magnesite. 

Reference:  State  Mineralogist  Eeports  XII,  XIII.     Bulletin  38. 

There  is  no  crude  magnesite  handled  on  the  market.  It  is  all  calcined 
and  ground  before  using.  However,  in  the  statistical  reports,  figures 
for  crude  ore  at  the  property  are  used  in  all  cases.  To  arrive  at  this  it 
has  been  found  that  calcined  magnesite  has  an  average  value  of  $25  per 
ton.  Two  and  one  half  to  two  and  one  fourth  tons  of  the  crude  ore 
make  one  ton  of  the  calcined  product ;  therefore,  the  arbitrary  value  of 
$10  per  ton  is  used. 

During  the  year  1912  the  output  of  crude  magnesite  in  California 
amounted  to  10,512  tons  having  a  value,  according  to  the  above  assump- 
tion, of  $105,120. 

Besides  the  counties  noted  below,  which  reported  a  production  of  this 
material,  depasits  are  located  in  Alameda,  Mendocino,  Napa,  San  Benito,

Onyx  and  travertine  marble  were  produced  in  California  to  the  value 
of  $91,400  between  the  years  1887  and  1896.  During  the  past  sixteen 
years  there  has  been  no  production  of  this  kind  of  building  stone  in  the 
State,  although  many  partially  exploited  deposits  exist  in  a  score  of 
counties.  Practically  all  the  onyx  and  travertine  now  used  on  the  coast 
is  imported  from  Mexico. 
Sandstone. 

Reference:  State  Mineralogist  Report  XII.     Bulletin  38. 

Sandstone  deposits,  developed  to  a  greater  or  less  extent,  are  to  be 
found  in  twenty -two  counties  of  the  State.  But  five  of  these  counties 
reported  a  production  during  1912  and  the  total  output  of  66,487  cubic 
feet  with  a  spot  value  of  $22,574  is  a  large  decrease  from  the  annual 
amount  marketed  in  previous  years.  The  quality  of  the  California 
sandstone  is  undoubtedly  good  and  in  most  cases  is  dark  in  color.  The 
decreased  production  is   directly   attributable  to  two   facts:   (1)    the

Serpentine. 

Reference:  Bulletin  38. 

Serpentine  has  been  quarried  both  as  a  building  and  as  an  ornamental  ] 
stone  in  various  parts  of  California  during  the  past  twenty  years.     In 
most  cases,  however,  it  lacks  sufficient  brightness  of  color  to  be  desirable 
for  ornamental  purposes,  and  has  too  many  cracks  and  impurities  to! 
make  a  first-class  building  stone.     The  value  of  all  the  serpentine  pro-;

Slate  production  in  California  had  its  beginning  in  1889  and  has  beehj 
continuous,  in  greater  or  less  amount,  up  to  1911,  since  when  no  pro-1 
duction  has  been  reported.  The  output  has  been  rapidly  declining  ihi 
recent  years.  Many  large  deposits  of  slate  are  known  in  the  State,  but; 
its  greatest  use  in  the  past  has  been  as  a  fireproof  roofing,  and  the] 
various  brands  of  "ready  roofing"  which  have  been  placed  on  the 
market  in  recent  years  have  hurt  the  industry  seriously.

In  previous  reports  these  materials  have  been  handled  separately,  but 
it  has  been  found  that  from  the  standpoint  of  the  producer  they  overln  n 
to  such  an  extent  that  it  is  much  more  satisfactory  to  group  them  as  h 
been  done  in  this  report. 

In  so  far  as  it  has  been  possible  to  do  so,  granite  and  crushed  rock  pro- 
duction has  been  subdivided  into  the  various  uses  to  which  the  product 
was  put.  It  will  be  noted,  however,  that  in  both  instances  a  very  large 
percentage  of  the  output  has  been  tabulated  under  the  heading  *' Un- 
classified.'^    This  is  necessary  because  of  the  fact  that  many  of  the 


STATE    MINING   BUREAU    STATISTICS.  29 

producers  have  no  way  of  telling  to  what  specific  use  their  rock  was  put 
after  they  have  quarried  and  sold  the  same. 

Thirty-seven  counties  reported  a  production  of  this  class  of  material 
.luring  1912  against  34  counties  in  1911.  The  value  of  the  1912  output 
shows  a  total  of  $5,473,928,  or  a  30  per  cent  increase  over  the  1911  pro- 
duction of  $4,176,918.  Not  only  did  the  total  value  make  such  a  great 
advance,  but  every  item  shows  a  healthy  increase,  and  with  very  few 
.exceptions  the  county  totals  mark  a  corresponding  progress. 

!iOS  Angeles  County  led  all  others  in  1911  in  this  branch  of  the 
mlustry  with  a  product  valued  at  $536,876.  For  1912  three  counties 
•  xcoeded  this  figure,  Los  Angeles  again  leading  with  a  total  of  $955,668; 

n  Bernardino  second  with  an  output  valued  at  $580,824,  and  Riverside 
I  ounty  third  with  a  production  of  $567,309. 

The  total  is  made  up  of  the  following — all  values  being  for  the  crude 
material  at  the  property :

CHAPTER  FIVE 


INDUSTRIAL  MATERIALS. 


Asbestos. 

Reference:  State  Mineralogist  Reports  XII,  XIII.  Bulletin  38. 
New  uses  and  applications  of  manufactured  asbestos  jjroducts  are 
constantly  being  made,  and  this  branch  of  the  mineral  industry  will 
some  day  be  an  important  one  in  California.  Ninety  per  cent  of  the 
crude  asbestos  used  in  the  United  States  is  imported,  and  while  man} 
deposits  and  surface  indications  of  the  mineral  have  long  been  known 
in  this  State,  it  is  only  recently  that  development  work  of  any  import- 
ance has  been  undertaken  along  these  lines.  The  prices  obtainable  for 
this  product  vary  widely,  depending  upon  the  quality  of  the  fibre. 
Production  for  the  year  1912,  as  reported  to  the  State  Mining  Bureau, 
amounted  to  90  tons,  having  a  spot  value  of  $2,700  as  compared  with 
125  tons  valued  at  $500  in  1911.  Long  fibre  asbestos,  suitable  to  tli> 
manufacture  of  tapestries,  etc.,  is  worth  as  high  as  $200  per  ton. 

Barytes. 

Reference:  State  Mineralogist  Report  XII.     Bulletin  38. 

Baryte  is  used  principally  in  the  paint  industry,  in  the  manufacture 
of  paper  and  rope,  in  tanning  leather  and  the  refining  of  sugar.  Tin 
demand,  although  comparatively  small,  is  increasing.  Crude  baryt'^ 
command  a  price  of  about  $5  per  ton,  at  the  propert3\ 

Deposits  of  this  mineral  are  known  in  Butte,  Mariposa,  San  Bernar 
dino  and  Shasta  counties.  Total  production  in  the  State  for  the  year 
1912  amounted  to  564  tons  valued  at  $2,812,  as  compared  with  the  1911 
output  of  309  tons  worth  $2,207. 

Before  marketing  barytes  the  product  is  usually  sorted  and  ground 
and  in  this  condition  it  brings  a  spot  price  of  from  $10  to  $14  per  ton 

Bauxite. 

Reference:  Bulletin  38. 
Bauxite,  the  ore  from  which  metallic  aluminum  is  derived,  has  been 
discovered  in  large  quantity  in  southern  California,  and  small  deposits 
are  also  known  in  other  parts  of  the  State.     No  ore  has  been  producet 
and  sold,  to  date,  although  the  outlook  for  such  a  condition  is  favorabl< 
and  the  increased  uses  which  are  continually  being  found  for  this  met.i 
practically  guarantee  another  addition  to  California's  long  list  of  profit 
able  mineral  products.

t  one  time  or  another  in  the  history  of  the  State,  pottery  clay  has 
n  quarried  in  thirty-three  of  its  counties.  In  this  report  "pottery 
clay"  refers  to  all  clays  used  in  the  manufacture  of  red  and  brown 
(  arthenware,  flower  pots,  tiling  of  all  descriptions,  architectural  terra 
cotta,  sewer  pipe,  etc.,  and  the  figures  for  amount  and  value  are  relative 
to  the  crude  material  at  the  pit,  without  reference  to  whether  the  clay 
was  sold  in  the  crude  form,  or  whether  it  was  immediately  used  in  the 
manufacture  of  any  of  the  above  finished  products  by  the  producer. 
The  production  as  reported  by  operators  for  the  year  1912  amounted 
I  to  199,605  tons  valued  at  $215,683  as  compared  with  an  output  of 
224,576  tons  worth  $252,759  in  1911,  a  slight  decrease  both  in  amount 
and  value.

the  j^ear  1912  is  as  follows :

Feldspar. 

The  feldspars  occur  as  constituents  of  nearly  all  rocks.  The  feldspar 
of  commerce,  however,  is  all  obtained  from  pegmatites,  where  the 
crj^stals  are  large  enough  to  admit  of  more  or  less  sorting.  The  better 
grades  of  feldspar  are  used  in  pottery  manufacture  and  in  the  making 
of  various  enamel  w^ares.  Where  a  high  per  cent  of  impurities  is 
present  the  material  is  ground  coarsely  and  used  in  the  manufacture  of 
"ready  roofing,"  "chicken  grit,"  etc.  Small  quantities  are  used  in 
glass  making,  and  as  an  abrasive  in  scouring  soap.  Attempts  have  been 
made  to  prove  the  value  of  the  potash  feldspars  as  fertilizer. 

Feldspar  was  first  commercially  produced  in  California  in  1910. 
During  the  year  1912,  1,382  tons  were  quarried  and  sold,  the  crude 
material  at  the  property  having  a  value  of  $6,180,  as  compared  with  the 
output  of  1911  amounting  to  740  tons  worth  $4,560.

36  MINERAL   INDUSTRY   OF    CALIFORNIA. 

Fuller's  Earth. 

Beference:  Bulletin  38. 
Fuller's  earth,  so  named  from  its  earliest  use  in  fulling  wool,  is  a 
rather  rare,  soft,  friable  rock  whose  value  depends  altogether  on  its 
texture  and  its  filtering  and  absorbent  properties.  It  has  no  definite 
composition,  mineralogically,  its  physical  properties  rather  than  a  chem- 
ical analysis  determining  its  commercial  value.  Fuller 's  earth  was  first 
produced  in  the  United  States  in  the  early  nineties,  and  has  been  mined 
and  marketed  in  a  small  way  in  California  annually  since  1899.  Dur- 
ing 1912  the  output  amounted  to  876  tons  having  a  spot  value  of  $6,500 
as  compared  with  the  production  of  the  previous  year  of  466  tons  worth 
$5,294,  or  an  increase  in  amount  of  410  tons  and  in  value  of  $1,206. 

Gems. 

Reference:  Bulletins  37,  64. 

Gem  production  in  California  has  shown  a  steady  decline  for  the  past 
two  or  three  years.  Seven  counties  reported  a  production  value  at 
$23,050  for  the  year  1912  as  against  eight  counties  which  produced  gems 
worth  $51,824  in  1911.  These  values  are  for  rough,  uncut  stones  at  the 
property,  and  are,  of  course,  only  a  small  per  cent  of  the  selling  prices 
received  for  the  stones  when  they  are  finished,  cut  and  mounted.  The 
figures  given  in  the  following  table  are  the  result  of  consultation  with 
producers  and  dealers  of  this  class  of  material  throughout  the  State. 

Gem  deposits  are  located  in  many  portions  of  the  State,  and  the  pos- 
sible yield  is  very  large.  Unlike  the  '^ precious"  stones,  however,  there 
is  no  definite  value  obtainable  for  these  native  gems;  the  demand  is 
largely  from  the  tourist  trade  and  is  exceedingly  irregular,  and  there  is 
a  constant  and  growing  competition  with  ''paste"  gems  of  every  kind 
as  well  as  with  a  growing  list  of  artificially  produced  "stones." 

The  decline  in  production  is  not  due  to  the  above  causes  alone.  There 
was  a  large  overproduction  of  rough  stones  in  1910  and  in  several 
instances  it  is  true  that  a  stock  of  gems  from  that  year  is  still  on  hand 
and  uncut.  On  account  of  this  overproduction,  and  the  quietness  of  the 
business  generally,  one  of  the  large  firms  which  has  been  interested  in 
gem  mining  in  the  State  for  years,  withdrew  from  the  field  altogether. 
Their  output,  alone,  for  the  year  1.910  was  greater  than  the  entire  pro- 
duction during  1912. 

Notwithstanding  the  stagnant  condition  of  this  branch  of  the  mineral 
industry,  as  a  whole,  considerable  development  work  was  carried  on  last 
year,  Fresno  and  Riverside  counties  increased  their  production  and 
San  Bernardino  County,  which  reported  no  output  whatever  in  1911,

Graphite. 

Reference:  State  Mineralogist  Report  XIII. 

No  natural  graphite  was  produced  in  California  during  1912  although 
there  are  deposits  of  the  mineral  located  in  several  counties  in  the  State, 
and  the  owners  of  one  property  reported  development  work  having  been 
done  in  the  course  of  the  year  with  a  possible  output  for  1913.  Graphite 
deposits  have  been  discovered,  and  exploited  to  some  extent,  in  the 
following  counties:  Fresno,  Los  Angeles,  Mendocino,  San  Bernardino, 
Siskiyou,  Sonoma,  and  Tuolumne. 

The  demand  for  graphite  shows  a  steady  increase.  Imports,  largely 
from  Mexico  and  Ceylon,  amount  to  about  $2,000,000  annually.  On 
account  of  its  infusibility  and  resistance  to  action  of  molten  metals, 
graphite  is  very  valuable  in  the  manufacture  of  crucibles;  it  is  also 
largely  used  in  the  manufacture  of  electrical  appliances,  as  a  steam 
packing,  as  a  lubricant,  in  manufacture  of  paint  and  lead  pencils,  and 
in  many  other  ways.  Prices  obtainable  vary  widely,  depending  upon 
the  grade  of  the  product,  and  upon  its  being  amorphous  or  crystalline. 
The  lowest  grades  bring  about  $10  per  ton,  and  from  this  figure  prices 
range  up  as  high  as  $200  for  the  pure  crystalline  variety. 

A  few  years  ago  only  crystalline  graphite  of  superior  quality  could 
be  used  in  many  of  the  arts  and  manufactures.  Now  inferior  mineral 
may  be  concentrated  by  flotation,  but  the  discovery  that  a  fair  grade  of 
graphite  could  be  manufactured  from  a  good  grade  of  coal  has  seriously 
hurt  the  mining  of  graphite,  and  lowered  the  price  so  that  inferior 
mineral  scarcely  finds  a  sale,  or  can  be  concentrated  at  a  profit.

Gypsum. 

Reference:  Bulletin  38. 

Gypsum  is  used  in  the  manufacture  of  plaster  of  paris,  in  the  paper 
and  glass  industries,  as  a  wall  plaster,  and  to  some  extent  as  a  fertilizer. 
Gypsum  occurs  most  commonly  as  the  well  known  "rock  gypsum," 
although  it  is  often  foimd  in  the  highly  crystallized  form  known  as 
selenite  as  well  as  in  the  fibrous  state  when  it  is  known  as  satin  spar. 
The  material,  as  it  is  quarried  in  California,  commonly  carries  a  con- 
siderable per  cent  of  impurities  in  the  form  of  clay,  limestone,  etc.  It 
is  ordinarily  ground  and  calcined  before  being  marketed. 

Gj^sum  production  for  the  year  1912  amounted  to  37,529  tons,  the 
crude  material  having  a  spot  value  of  $117,388,  as  compared  with  the 
1911  output  of  31,457  tons  worth  $101,475,  showing  that  the  demand  for 
the  year  had  an  upward  trend. 

Four  counties  reported  production,  as  will  be  seen  by  the  following 
table,  although  deposits  of  this  mineral  are  located  in  Butte,  Colusa, 
Fresno,  Los  Angeles,  Orange,  Riverside,  San  Benito,  San  Luis  Obispo, 
Santa  Barbara,  Tulare,  and  Ventura  counties,  as  well.

Infusorial  earth,  also  known  as  diatomaceous  earth,  tripoli  and  trip- 
olite,  occurs  in  California  very  extensively.  Deposits  of  importance  are 
located  in  Los  Angeles,  Monterey,  Orange,  San  Benito,  San  Bernardino, 
San  Luis  Obispo,  Santa  Barbara,  Shasta,  and  Tehama  counties. 

The  production  for  1912  amounted  to  4,129  tons  valued  at  $17,074,  as 
compared  with  2,194  tons  valued  at  $19,670  quarried  and  sold  during 
the  previous  year.     Only  two  counties  contributed  to  the  total :

Limestone. 

Reference:  State  Mineralogist  Reports  IV,  XII.    Bulletin  38. 

Eleven  counties  reported  a  production  of  limastone  in  1912  amounting 
to  613,375  tons  worth  $570,248  at  the  quarry.  This  is  a  decided  increase 
over  the  1911  production  when  thirteen  counties  contributed  to  a  total 
output  of  516,398  tons  valued  at  $452,790. 

Limestone  is  used  as  a  flux  by  smelters ;  in  the  refining  of  sugar ;  in 
manufacture  of  carbonic  acid;  as  a  fertilizer  for  ''sour"  soils;  and  in 
the  manufacture  of  glass,  paper  and  mineral  wool,  and  in  other  ways. 

These  figures  represent,  as  far  as  it  has  been  possible  to  make  them 
do  so,  limestone  used  as  such.  If  operators  report  limestone  production 
which  has  been  crushed  and  used  as  macadam,  it  has  been  classified  as 
macadam  in  this  report  and  not  as  limestone.  When  the  stone  has  been 
quarried  for  use  in  the  manufacture  of  cement  such  tonnages  have  been 
excluded  altogether  here  as  it  would  be  a  duplication  of  values  to  add 
both  the  cement  and  limestone  figures  in  the  general  total.  Many  of  the 
reports  received  by  the  State  Mining  Bureau,  however,  make  no  definite 
mention  of  the  use  to  which  the  material  w^as  put,  and  unless  otherwise 
known,  such  data  comprises  the  following  tabulation  which  apportions

Manganese. 

Reference:  State  Mineralogist  Reports  XII,  XIII.     Bulletin  38. 

Manganese  ores  are  found  widely  distributed  throughout  the  State 
and  a  production,  usually  small,  has  been  annually  reported  for  the  past 
quarter  of  a  century.  During  1912  the  output  amounted  to  only  22  tons 
valued  at  $400,  the  material  being  marketed  from  Alameda  and  Plumas 
counties.  Manganese  is  used  most  extensively  in  the  steel  industry; 
minor  uses  are  in  the  paint,  glass  and  pottery  industries,  in  chem- 
istry, etc.

Mica. 

Reference:  State  Mineralogist  Report  II.     Bulletin  38. 

According  to  the  records  of  the  State  Mining  Bureau  the  total  pro-    { 
duction  of  mica  in  California  has  been  but  150  tons  valued  at  $9,300.    j 
This  output  was  recorded  during  the  years  1902,  1903,  1904.     Most  of    ; 
the  mica  found  in  the  State  to  date  has  been  of  too  poor  a  grade  to  find , 
a  ready  market.     A  discovery  of  this  material  in  Los  Angeles  County, 
has  been  recently  reported,  although  but  little  development  has  been 
done  to  ascertain  its  real  value. 

Lithia  mica  was  produced  in  San  Diego  County,  1900-1905,  but  none 
has  been  sold  since.  This  mineral  is  used  in  the  manufacture  of 
artificial  mineral  water,  in  making  effervescing  lithia  tablets,  and  to 
some  extent  in  manufacturing  ''fireworks." 

Mineral   Paint. 

Reference:  State  Mineralogist  Reports  XII,  XIII.     Bulletin  38. 

Mineral  paint  to  the  amount  of  300  tons  having  a  spot  value  of  $1,800 
was  produced  in  California  during  1912.  This  figure  applies  to  the* 
crude  ore.  This  is  an  increase  over  the  1911  figures  of  114  tons  in 
amount  and  $616  in  value.  Mineral  paint  deposits  have  been  dis- 
covered in  the  following  counties :  Butte,  Calaveras,  Los  Angeles,  Napa, 
Nevada,  Placer,  Riverside,  Siskiyou,  Sonoma,  Stanislaus,  Trinity  and 
Yuba.  There  has  been  a  small  annual  output  of  this  material  in  thei 
State  since  1890,  at  which  date  the  first  production  was  reported. 

Mineral   Water. 

Reference:  State  Mineralogist  Reports  VI,  XII,  XIII. 

Eighteen  counties  reported  a  commercial  production  of  mineral  water 
during  1912  to  the  amount  of  2,497,794  gallons  valued  at  $529,384. 
These  figures  refer  to  mineral  water  actually  bottled  and  sold.  Hun-, 
dreds  of  thousands  of  gallons  are  used  at  the  springs  for  bathing  and; 
other  purposes  of  which  no  reliable  data  can  be  compiled,  and  millions! 
of  gallons  annually  run  to  waste. 

Prices  obtained  for  the  different  waters  vary  greatly  because  of  che 
great  difference  in  the  analysis  of  the  water  from  the  several  springs 
anrl  the  consequent  demand  for  same.

One  hundred  tons  of  pumice  were  produced  in  California  during 
1912  having  a  spot  value  of  $25  per  ton.  Deposits  of  this  material 
have  been  long  known  in  various  parts  of  the  State  but  only  once  before

Most  of  the  glass  sand  used  in  the  State  is  imported,  although  th( 
domestic  production  is  increasing  owing  to  the  development  of  deposits 
of  better  grades  of  material  than  formerly.  During  1912  the  output 
amounted  to  13,075  tons  valued  at  $15,404,  at  the  property,  as  coraparoc

Soapstone. 

Reference:  State  Mineralogist  Report  XII.  Bulletin  38. 
Small  amounts  of  soapstone  have  been  marketed  in  California  inter 
mittently  since  1893.  The  industry  has  never  been  developed  to  anj 
great  extent  as  yet,  although  the  possible  production  is  quite  large 
During  1912  the  output  amounted  to  1,750  tons  with  a  spot  value  oj 
$7,350  for  the  crude  material.  It  is  used  in  making  paper,  soap,  lubri

Deposits  of  borax  are  known  in  Inyo,  Kern,  Lake,  Los  Angeles, 
Imperial,  San  Bernardino,  Solano,  Tehama,  and  Ventura  counties.  In 
ilie  desert  portions  of  the  State  its  occurrence  is  more  or  less  common 
in  the  beds  of  ancient  lakes.  In  other  places  it  is  mined  as  an  ore, 
chiefly  colemanite,  which  occurs  in  vein-like  masses.  The  output  in 
California,  which  is  the  sole  domestic  source  of  borax,  in  1912  amounted 
to  42,135  tons  valued  at  $1,122,713  as  compared  with  the  1911  output 
of  50,945  tons  worth  $1,456,672. 

The  above  tonnage  refers  to  the  crude  ore  and  the  value  is  determined 
by  the  available  boracic  acid  present,  which  is  worth  one  dollar  per  unit. 

N  itrates. 

Reference:  Bulletin  24. 
Sodium  nitrate  deposits  of  unknown  extent  have  long  been  known  in 
that  portion  of  San  Bernardino  and  Inyo  counties  commonly  called  the 
Death  Valley  region.     There  has  never  been  a  commercial  production 
of  this  salt  in  California. 

Potash. 

A  great  deal  of  interest  has  been  taken  recently  in  occurrence  of 
potash  in  the  desert  regions  of  the  State.  The  only  literature  on  the 
■subject  is  in  the  form  of  a  few  brief  reports  by  the  U.  S^  Geological

California,  to  date. 

Salt.

The  California  salt  output  is  derived  from  the  following  sources: 
The  waters  of  the  Pacific  Ocean  by  evaporation,  this  branch  of  the 
industry  being  carried  on  principally  on  the  shores  of  San  Francisco 
Bay,  as  well  as  at  Long  Beach  and  San  Diego ;  from  the  old  lake  beds 
from  the  desert  portions  of  the  State,  where  many  thousand  acres  of
